Abstract
A method of forming a reversible color image of forming a multi color image to a reversible heat sensitive color recording medium in which recording layers each containing independently a plurality kinds of reversible heat color forming compositions having tone of formed color and color erasure starting temperature different from each other are formed on a support, the method comprising forming colors of all the compositions in the initial state and heating the color formed compositions not imagewise at different temperatures thereby erasing the color of the composition (recording layer 2). The color image can be formed simply and rapidly at a high energy efficiency.
